The thrust bearings are from mcmaster carr: 5909k41

The plate is 1/4" thick.

There are actually two thrust bearings and a plastic sleeve that make up the pivot bearing. The 1/4" plate is sandwiched between two thrust bearing assemblies. The assembly was shimmed to give the thrust bearings a pre-load. This removes the wobble. The plastic sleeve bushing keeps the "spool" of the pivot from contacting the aluminum plate. I'll ask one of the students to put up a screenshot of the cross section to clarify.
